Mild Weather Brings Up The Bulbs

Are your bulbs bursting? The recent warm spell may just stick around long enough to trick your bulbs–and perhaps a few other plants–into thinking it’s spring. This is the time of year when we normally expect temperatures to be cold enough to signal the hardening-off period to plants. And until quite recently, we were cold enough to start that process. Now, as the temperatures have been in the 50s and 60s for a while, some […]

Preparing the Garden for Winter

Many of us gardeners have mixed feelings about this time of year: sad to see another garden year draw to a close, but at the same time relieved to get a break from the chores of weeding, watering, pruning and more weeding. But before you hibernate, there are still a few more chores to take care of outdoors. Winter mulch isn’t necessary for all garden plants, but it can mean survival for some less hardy […]

Harvesting and Preserving Gourds

While gourds are often a part of today’s Halloween and Thanksgiving decorations, they date back to 2200 B.C., making them among the oldest cultivated plants in history. Since the times of the Egyptian tombs, their shells have been used as dippers or containers for grain storage; other types are edible when young and tender. The term “gourd” is most correctly applied to the hard-shelled members of the vine crops known as cucurbits and includes plants […]

October “In The Grow”

Q. My Sedum ‘Autumn Joy’ flops open in the center each fall and looks disastrous. What can I do?It’s too heavy to tie to a stake. Gary Kukulies, Lafayette, IN A.

Water Now to Prepare Plants for Winter

Dry summers are not that unusual in the Midwest, but this year’s weather pattern was a bit unusual in that much of the state experienced above normal precipitation in spring and early summer. But most areas found the flow of water shut off in mid to late summer. Many plants will be displaying their fall colors and dropping leaves in the next few weeks, but this is a critical time for plants to rehydrate themselves […]

Harvesting Grapes

Rosie Lerner, Purdue Consumer Horticulture Specialist Released September 24, 1998 One of the toughest things about growing your own grapes is beating the birds to the harvest! Could it be that the birds know something we don’t? Netting can be placed over a grape arbor to keep the birds away from the fruits. But don’t be too hasty in cutting the fruits to one-up the birds. Make sure your grapes are ripe before you harvest. […]
